Secure Cat-1 line monitoring

CAT-1 real-time Transmission Line Monitoring systems can be very quickly installed on existing or new lines. They measure ambient weather parameters and collect mechanical line-tension information. This vital information is then computed and forwarded in real time to the operator’s Control System (SCADA), indicating the actual additional available capacity and sag that the line can safely accept within the conductor’s design temperature. By providing advanced warnings when approaching limit conditions, CAT-1 helps to increase the reliability of network and gives information to quickly react and avoid severe problems.

Over 300 CAT-1 systems have already been deployed in North American and European transmission grids to provide information on conductor behavior and improve the reliability and the capacity of the grids.
